unknown species
Creature awaiting classification
An unknown species is a life form not yet identified or classified by science.
The term appears in biology when researchers encounter organisms they cannot match to existing records: The expedition discovered what appears to be an unknown species of deep-sea fish.
It also surfaces in speculative contexts—reports of cryptids or unidentified creatures: Witnesses described an unknown species lurking in the lake.
